Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542088, here are decompositions:

5 + 31542083 = 31542088
107 + 31541981 = 31542088
197 + 31541891 = 31542088
491 + 31541597 = 31542088
659 + 31541429 = 31542088
821 + 31541267 = 31542088
947 + 31541141 = 31542088
971 + 31541117 = 31542088

Showing the first eight; more decompositions exist.
